Abstract
The utility model discloses a middle support for the transmission system of a fire engine water pump. The utility model is characterized in that the middle support comprises a shaft, bearing arranged at both ends of the shaft, a carriage arranged outside the bearings, and coupling mechanism fixedly connected to both ends of the shaft; wherein the coupling mechanism are coupling flanges which are fixedly connected with the ends of the shaft through bolts, and gaskets are arranged respectively between each bolt and the shaft; the carriage is arranged and matched with the bearings and positioning clamp springs are arranged respectively between the carriage and each bearing; a plurality of connecting holes are arranged on the lug around each flange. The utility model has the advantages of simple and reasonable structure, fulfilling the working demand of the water pump and facilitating the acceleration arrangement of the transmission system, improving the continuous working capacity of the fire engine water pump.
Description
Technical field
The utility model relates to mechanical transmission fields, is a kind of fire-fighting truck water pump transmission system intermediate support.
Background technique
Water pump is the core component that fire-fighting truck is finished fire-extinguishing function concurrently, is equivalent to human heart.Generally, its power by a power output device (PTO) output, drives pump working through transmission shaft by engine in situ.Because water pump is away from power takeoff point, rotating speed is higher again, and transmission shaft generally will be divided into more piece.For guaranteeing transmission system operating noise, vibrations minimum, it is minimum to generate heat, and the ability of continuous operation is the strongest, keeps the constant angular layout except requiring system, and also the mode of structure with selected transmission shaft has direct relation.
Fire-fighting truck generally adopts the Cardan shaft and the supporting with it intermediate support of automobile chassis, but intermediate support that designs by the transmission system of chassis job requirement and incomplete the adaptation install and use in the water pump transmission system.Unreasonable uses, and is to cause homemade fire-fighting truck water pump driving unit fault rate height, a lasting not strong major reason of fight capability.
The model utility content
For addressing the above problem, the utility model provides a kind of fire-fighting truck water pump transmission system intermediate support that is suitable for the water pump transmission system at the general arrangement characteristics of fire-fighting truck.
The technological scheme that the utility model adopted is as follows:
Fire-fighting truck water pump transmission system intermediate support is characterized in that, comprise the axle, be installed on a two ends bearing, be located at the bearing of bearing outside and the coupling body that is connected and fixed with axle two.
Described coupling body is the shaft coupling flange.
Described shaft coupling flange is connected and fixed by bolt and shaft end, is provided with pad between bolt and the axle.
Described bearing cooperates installation with bearing, be provided with the location jump ring between them.
Circle bead around the described shaft coupling flange is provided with some attachment holes.
The utlity model has following advantage: (1) is simple and reasonable, and maximum functional rotating speed, safe working load, continuous running ability all satisfy the pump working requirement; (2) length is shorter, and the uniform acceleration that helps transmission system is arranged; (3) can reduce the rate of fault of homemade fire-fighting truck water pump transmission system, improve and continue fight capability.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further details
Fig. 1 is the utility model structural representation
Fig. 2 is the related transmission system schematic representation of the utility model
Embodiment
Fire-fighting truck water pump transmission system intermediate support as shown in Figure 1, comprise the axle 4, be installed on the axle 4 two ends bearing 2, be located at the bearing 3 of bearing 2 outsides and the shaft coupling flange 1 that is connected and fixed with axle 4 two.Shaft coupling flange 1 is connected and fixed by bolt 6 and axle 4 ends, is provided with pad 7 between bolt 6 and the axle 4.Bearing 3 cooperates installation with bearing 2, is provided with location jump ring 5 between them, can prevent that bearing 2 from sliding vertically.Circle bead around the shaft coupling flange 1 is provided with some attachment holes, in order to be located at transmission shaft 8 on flange be connected.
With reference to figure 2, the utility model is installed among the water pump transmission system, according to vehicle wheelbase length and water pump riding position, can use one or several intermediate support, two intermediate support have been used among Fig. 2, its two ends connect transmission shaft 8 respectively, and the output flange of power take-off 9 and the input flange of water pump 10 link together the most at last, realize transmission of power.By adjusting the setting angle of intermediate support, can realize that the uniform acceleration of transmission system is arranged.
